[0035] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0036] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.
[0037] The operating principle of the air conditioner involved in the embodiments of this application is described in detail below:
[0038] like Figure 1As shown, the compressor compresses the refrigerant, which is then delivered to the condenser. The high-temperature, high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature, high-pressure liquid refrigerant. The medium-temperature, high-pressure liquid refrigerant is then depressurized by the capillary tube (throttling unit) and becomes a low-temperature, low-pressure liquid refrigerant. The low-temperature, low-pressure liquid refrigerant is delivered to the evaporator, where it evaporates into a gas and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature, low-pressure gaseous refrigerant in the evaporator is delivered to the compressor and participates in the next cycle. When the air conditioner is cooling, the heat exchanger of the outdoor unit is the condenser, and the heat exchanger of the indoor unit is the evaporator; conversely, when the air conditioner is heating, the heat exchanger of the outdoor unit is the evaporator, and the heat exchanger of the indoor unit is the condenser.
[0039] The following describes the professional terms related to the embodiments of the present application:
[0040] Millimeter wave radar: A new type of wireless communication technology that has developed rapidly in recent years and has a wide range of applications in human body detection. Millimeter wave radar technology emits millimeter wave signals to the target object and receives the return signal, using the slight changes in the weak signal to extract relevant information about the target object, allowing for non-contact, non-invasive measurement and identification of the object.
[0041] Based on the above characteristics of millimeter wave radar, its application in human body detection includes the following aspects:
[0042] Health monitoring: By detecting physiological parameters such as heart rate, respiration, and body temperature, it can be used for health monitoring and disease prevention. For example, in the medical field, millimeter wave radar can be used to monitor a patient's heart or respiratory power, which can allow doctors to more accurately understand the patient's health status.
[0043] Posture recognition: By detecting and recognizing human posture, it can be further applied to human motion analysis, body position correction, and other fields, which can greatly help people's physical health and exercise effectiveness. For example, in a gym, millimeter wave radar can be used to detect whether an athlete's posture is accurate, so as to correct the athlete's incorrect posture and reduce exercise damage.
[0044] Human safety detection: Millimeter wave radar can conduct security checks on the human body, identify and detect dangerous goods and thermal energy substances, etc., such as detecting people carrying dangerous goods in airports and large public places, etc., to ensure safety. In addition, when the human body is detected to be in poor condition, the millimeter wave radar can also automatically send a signal to emergency personnel for emergency assistance.
[0045] In summary, millimeter wave radar has many applications in human detection, which can effectively improve people's quality of life and ensure the safety of the human body. With the development of millimeter wave radar technology, future applications will also be more extensive and diverse.
[0046] Compared with traditional infrared sensors, millimeter wave radar has the following advantages:
[0047] Low false touch, wide range: Compared with infrared sensor triggering, the false touch rate is reduced, breaking the limitations of mobile monitoring. Millimeter wave radar can realize target personnel presence perception, trajectory tracking and people counting in the office scene area.
[0048] No privacy leakage risk: Compared with cameras, millimeter wave radar does not involve privacy leakage and meets relevant privacy regulations. It is more suitable for office scenarios where cameras are not convenient to deploy, such as employee office areas, conference spaces, open spaces, and even highly sensitive places such as toilets and rest areas.
[0049] Strong environmental adaptability: Compared with infrared sensor equipment that relies on glass, plastic and other light-transmitting materials as a shell, ultrasonic equipment needs to avoid obstructions when in use. The limiting factors of millimeter wave radar are much less. It does not have to have a specific shape like an infrared sensor, nor does it have to be installed in a wide-angle place like a smart camera. With its penetrating properties, it can be integrated into different devices as a basic hardware to function.
[0050] In view of the technical problems in the related art that the angle adjustment of the deflector is too frequent and affects the service life of the stepping motor, the embodiment of the present application thinks that the number of adjustments of the angle of the deflector can be reduced, which not only reduces the heat generation of the stepping motor, but also improves the service life of the stepping motor.
[0051] The adaptive air supply method provided by the embodiment of the present application will be described in detail in combination with the drawings, specific embodiments and application scenarios.
[0052] As shown in Figure 2 The adaptive air supply method provided by the embodiment of the present application can include the following steps 201 to 203:
[0053] Step 201, acquiring a sub-area where a target object in a target air supply area of an air conditioner is located in real time by the millimeter wave radar.
[0054] Among them, the target object is any one of at least one object in the air supply area; the air supply area is evenly divided into a plurality of sub-areas according to the air supply angle, and each sub-area corresponds to the same air supply angle.
[0055] Exemplarily, the above-mentioned millimeter wave radar is a millimeter wave radar arranged on an indoor unit of an air conditioner, which is capable of positioning an object in a scanning area and determining relative position information between the millimeter wave radar and any target object.
[0056] For example, as shown in FIG. 1(A), the millimeter wave radar can be arranged on a side of an air outlet of an indoor unit of an air conditioner, which is used to measure the position of a user in a scanning area, so as to determine the area where the user is located. Figure 3
[0057] It can be understood that, when the air conditioner is running, the air supply range thereof is usually small due to the size of the air outlet, but the air conditioner can adjust the angle of the air deflector to supply air to different areas, so as to expand the air supply range. The area where the air conditioner can supply air is the air supply area of the air conditioner, which is usually a fan-shaped area of 150°. Based on the fan-shaped area, the area can be divided every 30°, i.e., each fan-shaped area of 30° is divided into a sub-area.
[0058] Step 202: in the case where the sub-area where the target object is located changes, determining the number of sub-areas crossed by the target object.
[0059] Exemplarily, in order to avoid that slight movement of the target object triggers adjustment of the angle of the air deflector of the air conditioner, the adjustment of the angle of the air deflector can be performed when the target object changes the area. Meanwhile, in order to avoid too frequent adjustment of the angle, the adjustment of the angle of the air deflector can also be performed after the target object completes the movement.
[0060] For example, as shown in FIG. 1(B), the air supply area of the air conditioner can be evenly divided into a plurality of sub-areas according to the angle, and the millimeter wave radar is used to monitor the area change of the user, so that the air conditioner can timely adjust the angle of the air deflector according to the area change of the user. Figure 3
[0061] Specifically, the above-mentioned step 202 can further include the following steps 202a1 to 202a3:
[0062] Step 202a1: in the case where the movement of the target object is detected, start recording the movement angle of the target object.
[0063] Step 202a2: in the case where the target object stops moving, stop recording the movement angle of the target object, and determine the target movement angle of the target object during the movement.
[0064] Step 202a3: according to the target movement angle, the sub-area where the target object is located before the movement, and the air supply angle of each sub-area, determine the number of sub-areas crossed by the target object during the movement.
[0065] For example, when the moving angle of the target object is 90°, and the blowing angle corresponding to each sub-region is 30°, it can be determined that the target object crosses three sub-regions.
[0066] It should be noted that, in the embodiments of the present application, when most (for example, 70%) of the target object is located in a certain sub-region, it can be considered that the target object is in the sub-region. The specific blowing scheme can be to blow into the sub-region and the two sub-regions adjacent to the sub-region.
[0067] Step 203: determining a target adjustment angle of the air conditioner deflector according to the moving direction of the target object and the number of sub-regions crossed by the target object, and controlling the deflector to adjust the angle according to the target adjustment angle.
[0068] For example, after the target object changes the region, the adjustment angle of the deflector can be determined according to the moving direction of the target object and the number of sub-regions crossed by the target object. The moving direction of the target object can determine the positive or negative value of the adjustment angle of the deflector, and the number of sub-regions crossed by the target object can determine the angle value of the adjustment angle of the deflector.
[0069] For example, after the deflector is adjusted according to the target adjustment angle, the air can continue to be blown into the sub-region where the target object is located, and the heat generation of the stepping motor can be reduced.
[0070] In a possible implementation, if there are multiple users in the blowing region, and the blowing range cannot cover all the users, the air conditioner can be controlled to perform air sweeping, so that each user can be blown by the air.
[0071] For example, after step 201, the adaptive blowing method provided by the embodiments of the present application can further include steps 204 to 206:
[0072] Step 204: in the case that the blowing region contains multiple objects, obtaining a target region in which the multiple objects in the blowing region are located; the target region includes multiple sub-regions.
[0073] Step 205: determining a region coverage range of the target region according to the distribution of each sub-region in the target region in the blowing region.
[0074] Step 206, in the case that the area coverage is greater than the maximum blowing range of the air conditioner, the target area is determined as the air sweeping area of the air conditioner, and the air sweeping of the air conditioner is controlled to enable the air conditioner to circulate air blowing into each sub-area of the target area.
[0075] Specifically, when any of the above objects appears area change, thereby causing the range of the target area to expand, at this time, the air sweeping area can be re-determined according to the method in the above steps, and the air sweeping angle of the air conditioner is adaptively adjusted.
[0076] Optionally, in the embodiment of the present application, the blowing area of the air conditioner can be regionally divided by the following steps.
[0077] Exemplarily, before the above step 201, the adaptive blowing method provided by the embodiment of the present application can further include the following steps 207 and 208:
[0078] Step 207, determining the number of sub-areas and the air blowing angle of each sub-area according to the ratio of the air blowing angle corresponding to the blowing area to the preset division angle.
[0079] Step 208, regionally dividing the blowing area according to the number of sub-areas and the air blowing angle of each sub-area, and dividing the blowing area into a plurality of sub-areas.
[0080] For example, taking the above blowing area as a 150° sector area as an example, if it is desired to divide the air sweeping area into 5 sub-areas, the blowing area can be divided into sub-areas according to a 30° sector area for each sub-area. The number of sub-areas is positively correlated with the number of times of adjusting the angle of the air deflector, that is, the more the number of sub-areas, the more the number of times of adjusting the angle of the air deflector.
[0081] Optionally, in the embodiment of the present application, since the user position obtained by the millimeter wave radar is the position of the user relative to the millimeter wave radar, in order to accurately determine the sub-area where the user is located, it is also necessary to convert the user position information obtained by the millimeter wave radar into relative position information of the user relative to the blowing area of the air conditioner.
[0082] Specifically, the above step 201 can include the following steps 201a and 201b:
[0083] Step 201a, obtaining the relative position information between the target object and the blowing area in the blowing area by the millimeter wave radar.
[0084] Step 201b, determining the sub-area where the target object is located according to the relative position information between the target object and the blowing area.
[0085] Specifically, the step 201a can include the following steps 201a1-201a3.
[0086] The step 201a1 acquires a first distance between a scanning area center line of the millimeter wave radar and a blowing area center line of the blowing area.
[0087] The step 201a2 acquires, by the millimeter wave radar, relative position information between the target object and the millimeter wave radar and a second distance between the target object and the scanning area center line.
[0088] The step 201a3 calculates a third distance between the target object and the blowing area center line according to the first distance and the second distance, and converts the relative position information between the target object and the millimeter wave radar into relative position information between the target object and the blowing area based on the third distance.
[0089] Exemplarily, as shown in Figure 4 To convert the relative position information between the target object and the millimeter wave radar into the relative position information between the target object and the blowing area of the air conditioner, it is necessary to first calculate the distance D (i.e., the first distance mentioned above, which can be obtained from the configuration information of the air conditioner or stored in the air conditioner by factory setting) between the scanning area center line of the scanning area of the millimeter wave radar and the blowing area center line of the blowing area of the air conditioner, and then calculate the distance (i.e., the third distance mentioned above) between the target object and the blowing area center line according to the distance between the target object and the scanning area center line (i.e., the second distance mentioned above). Finally, the relative position information between the target object and the blowing area can be obtained based on the third distance and the relative position information between the target object and the millimeter wave radar, and the sub-area where the target object is located can be accurately determined. The relative position information between the target object and the millimeter wave radar is mainly used to determine the distance between the target object and the millimeter wave radar, so as to further determine the distance between the target object and the air conditioner.
[0090] Specifically, the step 201b can include the following steps 201b1 and 201b2.
[0091] The step 201b1 calculates an angle between the target object and the blowing area center line according to the relative position information between the target object and the blowing area.
[0092] The angle between the target object and the blowing area center line is obtained based on the intersection of the boundary line of each sub-area and the blowing area center line.
[0093] Exemplarily, as shown in Figure 5As shown, the intersection of the boundary line of each sub-region and the center line of the air supply region is point O, and the angle formed by the line connecting the user and point O and the center line of the air supply region is the angle between the target object and the center line of the air supply region. The air supply angle corresponding to each sub-region is also calculated based on the intersection of the boundary line of the sub-region and the center line of the air supply region. Such a region division manner can ensure that the region size of each sub-region remains consistent.
[0094] Step 201b2, determining the sub-region where the target object is located according to the angle between the target object and the center line of the air supply region and the air supply angle of each sub-region.
[0095] For example, after obtaining the relative position information of the target object and the air supply region, the angle between the target object and the center line of the air supply region can be further calculated. Based on the angle between the target object and the center line of the air supply region and the air supply angle of each sub-region, the sub-region where the target object is located can be calculated.
[0096] For example, after determining the sub-region where the target object is located, when the target object moves, it can be more accurately judged whether the target object has changed the region, so that the air conditioner can timely and accurately adjust the angle of the air deflector.
[0097] The adaptive air supply method provided in the embodiment of the application first acquires the sub-region where the target object in the air supply region of the air conditioner is located in real time through the millimeter wave radar; then, in the case that the sub-region where the target object is located changes, the number of sub-regions crossed by the target object is determined; finally, according to the moving direction of the target object and the number of sub-regions crossed by the target object, the target adjustment angle of the air deflector of the air conditioner is determined, and the air deflector is controlled to perform angle adjustment according to the target adjustment angle; wherein the target object is any one of at least one object in the air supply region; the air supply region is evenly divided into a plurality of sub-regions according to air supply angles, and the air supply angle corresponding to each sub-region is the same. In this way, by reducing the number of adjustments of the angle of the air deflector, not only the heat generation of the stepping motor can be reduced, but also the service life of the stepping motor can be improved.
[0098] It should be noted that the adaptive air supply method provided in the embodiment of the application can be executed by an adaptive air supply device or a control module in the adaptive air supply device for executing the adaptive air supply method.
